Data Release Vernal pool inundation models
Authors: Jennifer M Cartwright; TL Morelli; Evan HC Grant
Date: 2020-06
This website provides an application for exploring modeling results from a U.S. Geological Survey (USGS) project titled Mapping Climate Change Resistant Vernal Pools in the Northeastern U.S. The purpose of this project was to improve understanding of the factors that control inundation patterns in vernal pools of the northeastern United States, so as to identify pools that might function as hydrologic refugia under climate change.

Altered flow regimes can contribute to dissociation between life history strategies and environmental conditions, leading to reduced persistence reported for many wildlife populations inhabiting regulated rivers. The Oregon spotted frog [Rana pretiosa] is a threatened species occurring in floodplains, ponds, and wetlands in the Pacific Northwest with a core range in Oregon, USA. All life stages of [R. pretiosa] are reliant on aquatic habitats, and inundation patterns across the phenological timeline can have implications for population success. We conducted capture–mark–recapture (CMR) sampling of adult and subadult [R. pretiosa] at three sites along the Deschutes River downstream from two dams that regulate flows. We related the seasonal extent of inundated habitat at each site to monthly survival probabilities using a robust design CMR model. We also developed matrix projection models to simulate population dynamics into the future under current river flows. Monthly survival was strongly associated with the extent and variability of inundated habitat, suggesting some within-season fluctuations at higher water levels could be beneficial. Seasonal survival was lowest in the winter for all three sites, owing to limited water availability and the greater number of months within this season relative to other seasons. Population growth for the two river-connected sites was most strongly linked to adult survival, whereas population growth at the river-disconnected site was most strongly tied to survival in juvenile stages. This research identifies population effects of seasonally limited water and highlights conservation potential of enhancing survival of particularly influential life stages.
Data Release Survival and sublethal effects of amphibians exposed to NaCl and brines from energy production
Authors: B J Tornabene; Creagh W Breuner; Blake R Hossack
Date: 2019-06-25 | Outlet: PANGAEA Data Publisher for Earth & Environmental Science
We investigated the influence of brines and NaCl alone at commensurate concentrations on three larval amphibian species that occur in areas with energy-related brine contamination. The dataset contains size information (mass in grams, snout-vent length in millimeters) of larval Boreal Chorus Frogs (Pseudacris maculata) and Leopard Frogs (Rana pipiens) and Barred Tiger Salamanders (Ambystoma mavortium) taken during 96-h lethal-concentration-50 experiments. Larvae were generally exposed to concentrations of brine or NaCl ranging from 0–8,000 mg/L increasing by 1,000 mg/L increments. Other associated dataset: https://doi.pangaea.de/10.1594/PANGAEA.913836
Data Release Corticosterone Mediates Lethal and Sublethal Effects and a Growth-Survival Tradeoff for a Larval Amphibian Exposed to Increased Salinity
Authors: B J Tornabene; Blake R Hossack; E J Crespi; Creagh W Breuner
Date: 2018-11-06 | Outlet: PANGAEA Data Publisher for Earth & Environmental Science
We investigated the influence of increased salinity on survival, growth, water content, and Corticosterone responses of larval Northern Leopard Frogs (Rana pipiens) by exposing them to environmentally-relevant salinity treatments for 24 days. We also inhibited Corticosterone for half of the replicates using mifepristone to determine if Corticosterone mediates effects of salinity and tradeoffs between traits. Other associated datasets:

Data Release Larval amphibian and site-water corticosterone, and site attributes, from wetlands affected by energy-related saline wastewaters
Authors: B J Tornabene; Blake R Hossack; E J Crespi; Creagh W Breuner
Date: 2021-09-24 | Outlet: figshare
We investigated the influence of salinity from energy-related saline wastewaters on CORT of three larval amphibians (Tiger salamanders, Leopard frogs, and Chorus frogs) in Montana and North Dakota where wastewater contamination is pervasive. We measured baseline and stress-induced CORT (pg/h) of amphibians exposed to a gradient of wastewaters using a novel, noninvasive technique. We also measured background corticosterone in site water in 2017 and 2018, and evaluated variance within and among wetlands in 2019. Three datasets are included. (1) Includes corticosterone and morphology measurements from larval amphibians taken in 2017 and 2018. (2) Includes background corticosterone measurements and attributes from sites in 2017–2019. (3) Includes background corticosterone measurements for 5 points along the perimeter of 6 sites in 2019 to evaluate variance within and among wetlands.

Data Release Seasonal median daily water depths for study wetlands in the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Research area, and the Upper Mississippi River study area from 2013-2018
Authors: W J Sadinski; Mark F Roth
Date: 2020-05-20 | Outlet: U.S. Geological Survey data release, https://doi.org/10.5066/P9H4VLEM
To relate water levels in our study wetlands to temperature, precipitation, wetland water depth, and amphibian calling activity, we installed one pressure logger in the deepest spot we could find in each wetland. Soon after thawing conditions allowed, we drove a plastic pipe (anchor pipe) into the sediments at the deepest location and secured another pipe to it that contained one pressure logger (Onset Computer Corporation Model U20-001-04 [Bourne, MA, USA]) suspended approximately 2.5 cm above the sediments. We installed additional individual pressure loggers in the upper part of the logger pipes (in air) at select locations to measure barometric pressure for calibrating the submerged loggers’ readings. We measured pressure once per hour and used software supplied by the logger manufacturers to upload and convert data to depth at the end of each season.

Data Release Annotated bibliography of grazing effects on amphibians and their habitats
Authors: Jennifer C Rowe; Christopher A Pearl; Michael J Adams; Brome McCreary
Date: 2020-03-04 | Outlet: Science Base
Livestock grazing is one of the most common land uses in the western United States, where multiple amphibians of conservation concern use habitats that are grazed. Despite the common intersection of grazing and sensitive amphibian species, there are very few reviews of research related to the issue. USGS researchers compiled and summarized literature pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on wetland-breeding species in the western United States. Users of the annotated bibliography can utilize an integrated search tool with user-defined criteria to query records and output results. This tool aids users in synthesizing research related to a range of specific questions and should assist land managers in evaluating and implementing grazing while maintaining habitat for wetland amphibians.

The data was gathered to determine the effects of cattle grazing on wetland water quality in the Klamath National Wildlife Refuge in Oregon. Surface water samples from sites representing a range of grazing histories were collected between June and October in 2017 and 2018. Samples were analyzed for nutrients (ammonia, nitrate plus nitrite, nitrite and orthophosphate), total coliforms, E. coli, enterococci and estrogenicity by US Geological Survey laboratories. Basic water quality parameters such as temperature, pH, turbidity and specific conductance were also collected in the field during each site visit. Quality assurance samples (blanks and replicates) as well as method information is also included in the data release.
